Cardio-pulmonary resuscitation machine with high-frequency ventilation function

Abstract

The invention discloses a cardio-pulmonary resuscitation machine with a high-frequency ventilation function. The cardio-pulmonary resuscitation machine comprises a bottom plate, an upright, an external chest compressor, a controller shell, a high-frequency ventilation electromagnetic valve and a high-frequency ventilation air source connector, wherein the upright is arranged on the side of the bottom plate, the external chest compressor is arranged on the upright, the controller shell is mounted at the top end of the upright or on the bottom plate, the high-frequency ventilation electromagnetic valve is mounted in the controller shell, and the high-frequency ventilation air source connector is arranged on the controller shell. An air outlet of the high-frequency ventilation electromagnetic valve is connected with the high-frequency ventilation air source connector through a pipeline, and the high-frequency ventilation electromagnetic valve is electrically connected with a compression ventilation controller in the controller shell. The cardio-pulmonary resuscitation machine has the advantages that on the basis of a conventional cardio-pulmonary resuscitation machine, the open type high-frequency ventilation function is added, so that the cardio-pulmonary resuscitation machine can be switched to use between an intermittent positive-pressure ventilation function and the open type high-frequency ventilation function, application range is broadened, and the cardio-pulmonary resuscitation machine is applicable to emergency treatment of various critical patients with respiratory failure and asphyxia.

Description

Technical field: [0001] The invention relates to a medical device, in particular to a cardiopulmonary resuscitator with high-frequency ventilation function. Background technique: [0002] Traditional cardiopulmonary resuscitation machines use intermittent positive pressure ventilation and chest compressions to perform cardiopulmonary resuscitation alternately at a certain ratio. The disadvantage is that intermittent positive pressure ventilation is closed ventilation and cannot be used for patients with open airways. Rescue; intermittent positive pressure ventilation will increase the airway and lung pressure, easily cause airway damage, cause a pressurization effect in the lungs, cause the alveoli to open and close repeatedly, generate shear force, and cause alveolar atrophy and inhalation at the end of expiration Excessive expansion of the terminal alveoli, causing lung tissue damage; increased lung pressure will cause increased thoracic pressure, resulting in reduced thor...

[0002] Traditional cardiopulmonary resuscitation machines use intermittent positive pressure ventilation and chest compressions to perform cardiopulmonary resuscitation alternately at a certain ratio. The disadvantage is that intermittent positive pressure ventilation is closed ventilation and cannot be used for patients with open airways. Rescue; intermittent positive pressure ventilation will increase the airway and lung pressure, easily cause airway damage, cause a pressurization effect in the lungs, cause the alveoli to open and close repeatedly, generate shear force, and cause alveolar atrophy and inhalation at the end of expiration Excessive expansion of the terminal alveoli, causing lung tissue damage; increased lung pressure will cause increased thoracic pressure, resulting in reduced thoracic venous return, which is not conducive to the rescue of critically ill patients with respiratory failure accompanied by hypovolemia and circulatory insufficiency; in the rescue of cardiopulmonary resuscitation During the process, when the patient resumes spontaneous breathing, the intermittent positive pressure ventilation cannot be synchronized with the patient's spontaneous breathing, resulting in man-machine confrontation; When the airway is not smooth, it is necessary to stop intermittent positive pressure ventilation and perform airway suction, which may easily cause hypoxemia in patients; the above-mentioned shortcomings cause the traditional cardiopulmonary resuscitation machine to have a single function and limited use
